3.2.13 Automatic Offset-Signal Adjustment of the Motor Current
Detection Signal (Fn00E)
Perform this adjustment only if highly accurate adjustment is required for reducing
torque ripple caused by current offset. The user need not usually use this function.
Note: Fn005 cannot initialize any value adjusted with Fn00E.
(1) Preparation
The following conditions must be met to automatically adjust the offset of the motor
current detection signal.
• The write prohibited setting (Fn010) must not be set to write-protect parameters.
• The main circuit power supply must be ON.
• All alarms must be cleared.
• The hardwire baseblock (HWBB) must be disabled.
• When an absolute encoder is used, the SEN signal is ON (high level).
• The servomotor power must be OFF.
(2) Operating Procedure
Use the following procedure.
• Be sure to perform this function while the servomotor
power is OFF.
• Execute the automatic offset adjustment if the torque rip-
ple is too big when compared with those of other SERVO-
PACKs.
